Tom Morello of Rage Against the Machine performs on eight tracks on Bruce Springsteen’s new album, ‘High Hopes’

Rage Against the Machine guitarist Tom Morello and Bruce Springsteen are something of best buddies at this point. In fact, on Springsteen’s upcoming 18th studio album, “High Hopes,” Morello laid down guitar lines on an impressive eight tracks.

When asked about the collaboration, Morello said it was an incredible experience to not only play guitar for Springsteen, but also share some vocals.

“I played on (Springsteen’s 2012 release] ‘Wrecking Ball,’ but I’m playing a lot and singing on this one…duetting too,” he told Rolling Stone. “I am a big Bruce Springsteen fan. It’s a tremendous honor to be able to collaborate in that way and to be asked to keep lending my guitar to songs is something I would have never dared to dream.”

Morello added that was originally only going to play guitar on one tune on “High Hopes,” but after a great first run, Springsteen continued to ask him back to play on additional songs. “Before the tour, I was sent the song ‘American Skin (41 Shots)’ to play guitar on,” he explains. “I did that in my home studio and Bruce seemed to like that very much. Then they sent me a couple more songs to have a go at or to solo on.”
